Question

Which graph represents the equation y = x – 3?
On a coordinate plane, a line goes through points (negative 3, 0) and (0, negative 3).
On a coordinate plane, a line goes through points (0, negative 1) and (1, 2).
On a coordinate plane, a line goes through points (0, negative 3) and (3, 0).

Answer 1

The third graph: the line through (0, −3) and (3, 0).

Reason: slope = (0 − (−3))/(3 − 0) = 1 and y-intercept = −3, so the equation is y = x − 3.
